Forollhogna is known as "the green National Park". The rolling hills and limestone bedrock provide for rich vegetation, a high diversity of species and plentiful space for grazing animals.
The area is characterized by a rich bird life, wild reindeer, grouse habitats and biodiversity. Significant pasture resources in mountains and valleys make the area an important in the agricultural region for Norway.
You’ll find plenty of sheep and cattle grazing in outlying areas with many of the farms still producing dairy. Local food and the transfer of traditional knowledge is important in Forollhogna. The long-term use of the countryside for dairy farming and grazing pastures for animals has been very influential on the landscape as well as has contributed to a great diversity of habitats, species and cultural heritage.
The National Park is named after the Forollhogna peak (1332 meters elevation) which looms in the otherwise rather calm countryside.
There are no marked hiking routes in the National Park, except the Pilegrimsleden route, which makes it very helpful having the Outtt map open. This area is for those that want to stroll on old, unmarked trails in gentle terrain, fish, hunt or just enjoy the peace and nature. Just outside of the National Park you will however find many exciting customized tours and adventures.
The National park's layout is almost like a snowflake where the pasture valleys extend into the mountainous area from many sides. There are therefore many gateways to the region. The plateau is protected as a National Park, while the farmland valleys are protected as conservation landscapes. Forollhogna National Park along with 8 adjacent landscape conservation areas were protected collectively in 2001.
Of the 22 selected cultural landscapes in the country, the largest in Forollhogna are: Budalen and Endalen in Midtre Gauldal, and Vangrøftdalen, Kjurrudalen and Setersjøen in Os Municipality.
